Indeed. Thank you, Keith. And having investigated further, I find that professional Argentine senior officers regarded what happened as a legitimate hazard of war to be anticipated:-

'Argentine Rear Admiral Allara, who was in charge of the task force that the Belgrano was part of, said, "After that message of 23 April, the entire South Atlantic was an operational theatre for both sides. We, as professionals, said it was just too bad that we lost the Belgrano". Captain Bonzo also told Middlebrook [author of a book about the incident] that he was not angry about the attack on his ship and "The limit [exclusion zone] did not exclude danger or risks; it was all the same in or out".'
